Apparatus and associated methods relate to a storage container and storage container lid configured for stowage and extraction of panels, the panels having complementary mating interfaces that cause the panels to stack onto one another as the panels enter the storage container lid, and to couple to one another as the panels are extracted from the storage container lid. In an illustrative example, the mating interface for the panels may include a first linearly decreasing section, a linearly increasing section, and a second linearly decreasing section that complements the mating interface of an adjacent panel. The panels may slide along a channel into and out of an opening in the storage container lid. A panel storage system may advantageously store panels in the lid of the storage container, while still providing access to the contents of the storage container by opening of the lid.
